On Ubuntu, the standard install of Mozilla Thunderbird does not have the option for Exchange accounts built in. In order to do so, we must install an add-in called ExQuilla.

Installing ExQuilla:

1. With Thunderbird open, click on the settings icon in the top right, and select Add-Ons
2. Using the search bar, look up ExQuilla
3. Install ExQuilla for Microsoft Exchange
4. This will require you to restart Thunderbird

Adding your UNT Exchange account:

1. With Thunderbird open, click on the settings icon in the top right, select Account Settings under Preferences
2. On the next window, click Account Actions at the bottom, and select "Add Mircosoft Exchange Account..."
3. Type in your email address and password, and click "Remember password"
4. Select "Login with email address (recommended)"
5. Next
6. For the Microsoft Exchange EWS URL, select Manual
   • https://outlook.office365.com/EWS/Exchange.asmx
7. ?Next
8. Finish
